Z homing issue
i'm back 😦
when i try to Z home from klipper, the front left stepper goes downwards, while the right and rear goes upwards. If i dont emergency stop on time, the bed will fall off from the tilt angle. You'd think it's a motor with reversed wiring but when i select x and y homing, the bed will lower an inch with no problems. All 3 motors go down the same amount. Any suggestions?

What happens when you select to home all axis at once?
it does the x first, then y, then z. not all at once. same issue when it gets to Z homing though.
Upload your printer.cfg
I think they uploaded it in the Unable to read tmc uart thread a bit ago, not sure if it's changed since then
about to board my flight, so can't review it right now.
i can do it again
Have you tried inverting (!) one of the z configs? I know you indicate that the step back for x and y has them all operating in the same direction, but your config looks right based on my quick look on my phone.
i thought about it, maybe i can test it by doing the Z1 only as that is the stepper having the issue
Can't open zip files on mobile
Android or iOS?
Cx File Explorer managed it on Android for me.
so i played around with adding ! to the motors, funny enough for a couple of the tests, even with the ! the motor still went the same direction. one thing i noticed is that the z homing will do the same 1 inch drop as the x and y, then proceed to drop on the same left motor again. is it a z homing issue that is tied to the bl touch? i haven't done anything to set up the bl touch yet other than removing # to include it. and setting the height in regards to the nozzle height. Actually i dont think i can do much without finishing the homing anyways.
zip are annoying for text files anyways
when i downloaded from klipper/moonsail, it zipped it. i left as is. i can unzip and repost.
oh weird, I don't remember mine doing that. No worries
Did you restart klipper after making changes to the printer.cfg?
